Two special things that come to mind about two domensions: in conformal field theory, it is only in the 2D case that you have an infinite number of conformal transformations available, which leads to tight constraints on your physical theory that you can leverage. The other thing is that in two spatial dimensions (and one temporal), gravity is an entirely topological theory. That doesn't make it trivial, but things don't depend on your Riemannian metric anymore.

Mr. Turin, with your scientific background and immense life of mind, I wonder what you would think of Amber Jobin’s work? Her Aether Arts is a fascinating brand (more like wearable art, quite experimental). I especially enjoy her Exobotany series (based on things like atmospheric readings of exoplanet Gliese-667e, imagined event horizons, etc.). Fun stuff! IAO-award-winning, too. I’d be most interested in your thoughts, whatever they turn out to be. 😀

Thank you, will definitely check it out.

Here is the origin story of “perfume space!” This makes me curious about the physics or geometry whereby fougeres give one dimensional men their second dimension.
